    "abstract": "The mechanism of ablation of solids by intense femtosecond laser pulses is\ndescribed in an explicit analytical form. It is shown that at high intensities\nwhen the ionization of the target material is complete before the end of the\npulse, the ablation mechanism is the same for both metals and dielectrics. The\nphysics of this new ablation regime involves ion acceleration in the\nelectrostatic field caused by charge separation created by energetic electrons\nescaping from the target. The formulae for ablation thresholds and ablation\nrates for metals and dielectrics, combining the laser and target parameters,\nare derived and compared to experimental data. The calculated dependence of the\nablation thresholds on the pulse duration is in agreement with the experimental\ndata in a femtosecond range, and it is linked to the dependence for nanosecond\npulses.",
